BOLSTER.

applicati@ ned Apri1f21,1923. serial No. eaaeeal ence being had to the accompanying drawings.

This invention relatesto improvements in bolstersv and more particularly to the im-` provements in the bolster construction employed in wagons or the like.

An important object of theinvention is to provide in the bolster construction a novel and improved stake `mounting whereby the stake is firmly held in. elevated position but may be readily shifted to inoperative position to permit unloading of the vehicle.

A further object of the invention is to provide an extensiblebolster, the length of which may be varied asv desired. A still further object ofthe invention is to provide an attachment for holsters lapplicable to the present construction of bolster and by means of which the bolster can be made extensible,- the attachment embodying a novel and improvedstake mounting whereby the stakes are lreadily slriftable -to operative or inoperative position and are positivelyy heldin the latter position..

These. and! other objects I attain kby the construction shown. in. the accompanying drawings, wherein for the purpose of illustration I have shown apreferred embodiment of my invention and wherein.:--V p Figure 1 is a perspective view of a bolster constructed in. accordance' with my invention Figure 2 is a fragmentaryv perspective showing the stake moved to the inoperative position. Y

Figure 3v is a sectionaly view taken through the end of the bolster andthe stake mountingf Figure 4 is a transverse sectional view takien substantially centrallyfof the bolster; an

Figure 5 is a'perspective View of the stake locking plate..`

Referring now' vmore particularly to the drawings, the -numeral 10v generally indicates ay bolster having extending from each end thereof spaced vertically disposed parallel fianges ,'11, connected attheir top ends with horizontallyl disposed flanges 12 vwhich are oppositely .directed `Pivotally mounted vbetween the flanges 11 and substantially filling the space therebetween is the lower end of a stake 13, the pivot being indicated at 14 and being adjacent `the lowerZ ends of the vertical flanges 11. vThe horizontal flanges 12 are provided with slots y15 communicating .withvertical-slots lbformecl in ztl'le'uppel" ends of the vertical flanges ,11, the slots 15 and 16 being immediately adj acentthe outer face of the stake .13 when the same is in operative or vertical position. V f

Mounted in the stake 13' isa bolt 17 the head of which isV arranged at the outer face ofthe stake, 'this bolt-having' mounted thereon between the head 'and'l thefface of the stakes a plate 187 the bolt extending through a slot 19 formed in the plate.'L Thel plate 18 is substantially T shaped, the slot- 19v being formed in the stem thereof-'and this stembai-ng of a width slightly less than the distance between adjacent faces ofthe flan-ges `11.

The upper end of the head 20 of the/'plate is provided with an outwardly extending horizontal flangel 21 and this head is Vof greater Width than the distance 'between the plates .11, accordingly,.when the stake is .vertically arranged and the plate 18 moved downwardly thereon,v the head 20` o -f this plate will engage lin the slots 15 and 16 locking .the Astake against movement between the flanges, the flange 21 serving as a handle for manipulation ofthe plate and by its engagement withY the horizontal flanges 12 to limit downward". movement o-f the plate. 'Ihe slot 191s of sufficient length so thateby engaging the flange 21 ofv the plate the plate may beelevated' so that'the lower edge of the heady clears.' the upper ends of the horizontal flanges 12,.,at which time the stake 13 may be rotated to inoperative position to permit iuiloading of the vehicle of which the Vbolster forms a part.

` In the construction of the bolster 10 I preferably employ as a body the ordinary bolster 22 of the vehicle,this bolster being cut off just inwardly of the ordinary stake openings thereof and having formed therein adjacent each Vendv an ope-ning ,2S-and having extended therethrough at its approximate center a transversely disposed guide bolt 2a. With this bolster as reconstructed I employ a pair of channel iron frames l25 .2 and 26, `the frame 26 having the channel thereof closely fitting and slidably receiving the bolster 22 and the channel'of the frame 25 closely receiving the frame 26 and slid-m mitting longitudinal shifting of the frames 25 and 26 but positively limiting this movement..` These side arms are further provided with a series of longitudinally spaced openings 28 arranged in aligned pairs, adapted for select-ive alignment with the openings 23 of the ends of the bolster and when soaligned combining with the bolster to receive securing pins 29'of any desired construction. i I

" In the construction of the frames 25 and 26 the side, arms of each of these frames at one end thereof are bent inwardly toward one another,v as indicated at 30, and subsequently outwardly to form thespaced flanges ll hereinbefore referred to. `The bight porf tions at these ends are continued outwardly tion, the bight portion thus Yserves to vform the horizontalfianges 12- hereinbefore referred to. 'From the foregoing it will be Yseen that bythe addition 4of the frames 25 and 26 abolster is provided which is longitudinally extensible, which may be secured inia'djusted position and .which affords at each end thereof a novel and improved stake mounting. It will furthermore beV obvious that this struc-ture is capable of some change and modification without materially departing from the spirit of my invention and I accordingly do not limit myself to such specific structure as hereinbefore set forth except as hereinafter claimed.

I claim i 1. In an extensible bolster, a bolster body having a guide bolt extending therethrough .approximately centrally thereof, a pair of channel iron frames, one rslidably fitting the bolster and longitudinally shiftable thereon and the other slidably fitting the first named frame, said frameshaving slots therein'receiving the ends of said guideV bolt, said bolster body having openings formed therein'adjacent the ends thereof, said frames being providedfwith aligned pairs of longitudinally spaced openings selectively alignable with the openings of the bolster body and retaining pins adapted for extension IthiC-lough aligned openings of the frames and o y.

`2,In a bolster, a stake mounting-.coniprismg a pair of vertically disposed spaced flanges extending outwardly-from the ends of thel bolster and between which the stake is pivotally mounted and swingable to oper- 3. In an extensible bolster1 a bolster body having a guide'bolt extending transversely therethrough approximately centrally thereof, a pair of inverted channel iron frames, one slidably fit-ting the bolster and longitudinally shiftable thereon and the other slidably fitting the first named frame, said frames havingslots formedin the arms thereofV receiving they ends of said lguide bolts, said bolster body having openings formed 'therein adjacent the ends thereof, said frames being provided in the, arms thereof with aligned'pair's of longitudinally spaced openingsselectively alignable with the openings ofthe bolster body and retaining pins adapted for extension through aligned openings of the frame andbody.

4. In a bolster, a stake mounting comprising a pair of vertically disposed flanges extending outwardly from the ends of the bolster and between which the stake is pivotallyV mounted and swingable to operative and inoperative position, said flanges having vertical'slots formed thereinandopening through .the upper ends thereofaligning with the outerface of the stake when in vertical position,` anda plate4 slidable upon the outer face'of the stake having portions engageable in said slots when the stake is in. vertical position.

5. In abolster, a stake mounting comprising a, pair of vertically disposed flanges VVextending .outwardly from the endsy ofy the bolster and between which the stake is pivotally mounted and. swingable to operative and inoperative position, said flanges having vertical slots formed therein andy opening through the upper ends thereof aligning with the outer face of the stake when in vertical position, and a plate slidable upon the outer face of the stake having portions enga-geable in said slots when the stake is in i vertical position, and horizontal flangeslsecured to the upper ends of the vertical flanges and extending in opposite directions therefrom, said horizontal flangeshaving slots formed therein communicating with the slots of their respective vertical flanges and into which the outer edges of saidplate extend. A n

6. In a bolster, a stake mounting comprising a pair of vertically disposedllangesextending outwardly from the ends of.` the bolster and between which the stake ispivotally mountedy and swingable to operative and inoperative position, said flanges having vertical slots formed therein and `epen- ,ing through the upper ends thereof align'- ing with the outer face of the stake when in vertical position, and a plate slidable upon the outer face of the stake having portions engagea-ble in said slots when the stake is in vertical position, and horizontal flanges secured to the upper ends of the vertical flanges and extending in opposite direct-ions therefrom, said horizontal flanges having slots formed therein communicating with the slots of their respective vertical flanges and into which the outer edges of said pla-te extend, said plate being provided with a horizontal fiange engaging the first ynamed horizontal fianges to limit downward movement of the plate.
